About

The Swift++ Project is an effort to build a compiler which translates source code in a Smalltalk-based language and generates binaries for the Swift and Objective-C environments, the goal being to leverage the work of the Swift community to port the ecosystem to various platforms: desktop computers, smartphones, servers, etc.

There are currently two repos the work is proceeding on:

• Swift++ the official project repository for the Swift++ compiler
• Swift Apple’s repo, where changes are tested until Swift++ build issues are resolved

Setup

Building Swift requires 20 separate repositories to be cloned into a source tree hierarchy. To get to a compiler which doesn’t require those repos, and the 70GB of storage space a full, debuggable build requires, the Swift++ build system must be weaned off Swift’s.

• Set up a development workspace for, and build, Swift.
• Either clone the proving-ground branch into the Swift workspace, or the official repo into a separate directory.
• Set an envirnoment variable LLVM_BUILD_DIR to point to the swift-llvm build directory. (EG, export LLVM_BUILD_DIR=”~/swift-source/build/Ninja-RelWithDebInfoAssert+swift-DebugAssert/llvm-macosx-x86_64”)
